Animation, I do not want the MoD anywhere near censorship. Not a chance. You are taking my comment out of context and actually you are scaring me with it now. I find your authoritarian approach actually quite terrifying.
My point was you need people who are capable of designing software that is as close to unhackable as you can get and lead their field; and even then I'm not convinced they could do it due to the limitations and side effects of trying to censor porn.
You need to understand the porn industry really led the development and expansion of the internet, because of the money it generated and thats what you are up against. One of the biggest industries on the internet which often sits outside the boundaries of the law as it is.
Not only that but the darker side of the internet, is populated by people who see it as a game to create chaos or to hack and protect the freedom of the internet as being uncensored. Its very anarchist and certainly does not respect authoritarian responses, even if its well intentioned and against porn and protecting children because they think it is about controlling people in general. You need to understand this mentality before you start thinking about massive government lead projects in this area.
FWIW, just an example of how its unlikely to work. Piratebay was banned and you can't access it through some ISPs because they filter it out. So what have they done. Changed the URL. Same for other banned sites, they just keep changing the URL and the people who are responsible for the filtering just can't keep up with it. If they can't manage it for one site, how do you think they will do it for thousands and thousands?
And if you filter sites where there are certain words you get real issues too. Its been pointed out to me in the past how the internet can have a positive effect with adult content; teenagers who are discovering their sexuality - particularly if they are gay or lesbian. They might not be accessing porn but they might be accessing adult content sites they give them support and understanding and actually help them rather than being a destructive force.
And the problem with censorship is at what point do you say that is termed as adult content and that isn't. The debate has focused on porn, but strictly speaking unless you codify that and explicitly can define that you have an issue, and even then people will find ways to just about get round the edges of that.
And thats before you even start thinking about the very minor issue that what X considers to be porn, is rarely exactly the same as what Y considered to be porn.
It really is a complete pie in the sky idea and you clearly lack very little real understanding of what you are proposing would actually involve or need and what problems and opposition it would face.
